How to restore original firmware on n7000?

Question

Android

I'm not very good at this at all.
I installed the CyanogenMod firmware on the n7000 (Samsung Galaxy Note "first") using the notorious CM official windows installer. And everything would be fine (*), but I decided to return to the stock version.
How to return "as it was" in a simple way?
It is possible for 2 *, I will then upgrade to 4 *. The data is not important, all phones and stuff are saved in the g-profile, the pictures are in the dropbox. Maybe this can be done through KIES (I'm a little afraid, I don't want to brick, very much)?
------------------
* But the battery drains like a toilet, the stock browser blinks the screen, 1tv hangs periodically, GMusic does not cache files, the camera can hang the device at the most necessary moment.
